Wednesday Morning Rambles: Midweek Storms, MJO Impacts On Late March Pattern…

I. The morning is off to a quiet, chilly start, but clouds will lower and thicken through the morning and rain will soon follow. Periods of moderate to heavy rain can be expected this afternoon into the early evening hours, including widespread 0.50″ to 1″ with a few locally heavier amounts.

Rain will become widespread across the region through the afternoon.
Most of central Indiana can expect between 0.5″ and 1″ by midnight.

II. A changeable weather day is on tap Thursday with a couple of rounds of storms expected- late morning and again during the evening and night. The initial round of storms will lift northeast across the state Thursday morning into early afternoon, courtesy of a warm front. Highs will flirt with 70° tomorrow afternoon once the storms move out.

A cold front will then sweep through the region during the overnight. Additional storms (some potentially strong to severe) will take place as the front moves through the region.

A few storms may be strong to severe as the cold front moves through Thursday evening-night.

III. We’ll turn MUCH colder, but at least the sunshine will return as we move through the weekend. Lows in the 20s can be expected.

IV. Our next storm system looks to arrive Tuesday. From this distance, it appears this will be a potent system, including strong winds and heavy rain.

V. Longer term, we continue to watch the various players align. The MJO looks to amplify and rumble into Phase 3 by late March. The movement through Phases 1-2 can at least generate transient cold for our neck of the woods before Phase 3 favors the brunt of the cold across the West. Interestingly, this is what the latest European ensemble is also showing.

Very Active Pattern Looms For Mid And Late March…

Before we get into the longer range weather pattern, rain this morning has been locally heavy in spots. Moving forward today, that rain will push east of the state and we’ll turn cooler. Temperatures will settle into the middle to upper 40s this afternoon across central Indiana.

Another couple of weak systems will scoot through the area as we push through the remainder of the work week. The first, tomorrow, will impact areas primarily to our north, however, a cold front will sweep through the state Thursday night and early Friday with light rain and an abrupt wind shift to the northwest. Rainfall amounts with the passage of this cold front should average only between a trace and 0.05″.

A third system will push east across the TN Valley Saturday into early Sunday. With marginally cold air in place across the Ohio Valley, precipitation may transition to wet snow or a mix of rain and snow along the I-70 corridor during this time frame. The northward extent of the precipitation shield is in question and we’ll have to keep a close eye on this system over the next couple of days.

As we look longer term, a tight thermal gradient is expected to setup shop across our region. This will force a cold pattern across the west with eastern seaboard warmth. We’ll be in that “back and forth” battle zone of sorts, locally.

What this will also do is help assist in a hyper storm track through the MS River Valley and Ohio Valley. Above to well above average precipitation is expected during the middle and latter part of March across our region.

Unfortunately, local landscaping companies, turf management, farmers, and others with ag interests are likely to experience delays as we move through the 2nd half of March and into early April.
